Called 500fastcash to repay the loan and sent it to their compliance department. Now no one will talk to me to pay it off. Any ideas

The Federal Trade Commission (FTC), the nation's consumer protection agency, is warning consumers to be on the alert for scam artists posing as debt collectors. It may be hard to tell the difference between a legitimate debt collector and a fake one. Sometimes a fake collector may even have some of your personal information, like a bank account number. A caller may be a fake debt collector if he:

?is seeking payment on a debt for a loan you do not recognize;
?refuses to give you a mailing address or phone number;
?asks you for personal financial or sensitive information; or
?exerts high pressure to try to scare you into paying, such as threatening to have you arrested or to report you to a law enforcement agency.

If you think that a caller may be a fake debt collector:

?Ask the caller for his name, company, street address, and telephone number. Tell the caller that you refuse to discuss any debt until you get a written "validation notice." The notice must include the amount of the debt, the name of the creditor you owe, and your rights under the federal Fair Debt Collection Practices Act.
If a caller refuses to give you all of this information, do not pay! Paying a fake debt collector will not always make them go away. They may make up another debt to try to get more money from you.?Stop speaking with the caller. If you have the caller's address, send a letter demanding that the caller stop contacting you, and keep a copy for your files. By law, real debt collectors must stop calling you if you ask them to in writing.
?Do not give the caller personal financial or other sensitive information. Never give out or confirm personal financial or other sensitive information like your bank account, credit card, or Social Security number unless you know whom you're dealing with. Scam artists, like fake debt collectors, can use your information to commit identity theft ? charging your existing credit cards, opening new credit card, checking, or savings accounts, writing fraudulent checks, or taking out loans in your name.
?Contact your creditor. If the debt is legitimate ? but you think the collector may not be ? contact your creditor about the calls. Share the information you have about the suspicious calls and find out who, if anyone, the creditor has authorized to collect the debt.
?Report the call. Contact the FTC and your state Attorney General's office with information about suspicious callers. Many states have their own debt collection laws in addition to the federal FDCPA. Your Attorney General's office can help you determine your rights under your state's law.

There is a Alex Hamilton Jr., Sr. and the 3rd with my number, this 500 fast cash calls, and I have told them to send something in writing showing Alex Hamilton Father or son owes them, and how much, and the y will be paid but, they refuse, claims they need Bank info over the Phone

I paid this 500cash the amount on a payment plan. After I paid it off off they told me I had another payment I said NO! this what you told me. They lied  to me and I feel like a fool. I just got a call from the.m HELLO!
They will never get another penny from me..

You will have to research the internet and find out if they are licensed in Washington DC and also who they are operated by.  Some sites say they are operated by the Modac tribe.  If they are operated by an indian tribe, they are illegal.  If they are not licensed in your state, they are illegal.  Also, if you inform them that you cannot receive personal calls at work and that they are putting your job in jeporady, they must take your work number off their calling list.  They do not have the right to jepordize your job!

I stupidly got an online payday loan, and have more than regretted it since! I got the loan 2 years ago, paid much more than what I borrowed and ended up closing my bank account, as they were slowly draining it. I spoke with a representative of the NC State Attorney General's office who told me that payday loans in NC, and that I am obligated to ONLY pay back what I borrowed!!  It is the law! Again, I have MORE than paid back what I borrowed and will NEVER EVER pay them one penny more.  These online payday loans are a very, very bad idea!  Steer clear from them.  They will relentlessly call to try and collect more money...even YEARS after the loan was taken out.  Such a pain in the butt!!

They call my number everyday .i just dont answer

Its united cash loans calling to collect a unpaid loan? I dont remember taking a loan out with them but they said i do....

PLease have these people stop calling.. They call every single day!

I keep receiving calls from 918-442-9101 asking for a fellow co-worker of mine. I say they have the wrong # and I eagerly give them her direct phone line. I just want to get them to stop calling me. This is NOT MY PROBLEM. But do you think they write this # down ???  Noooooo, because they keep calling ME. They refuse to identify themselves or the company name. I mentioned this situation to the co-worker and she just stared at me like a deer caught in headlights. I don't want to take this to management but I am getting really fed up !!!

Hello to all. Please do not answer when this number calls you. I recd a call from another place stating they were attorneys for pay day loans. To make a long story short. They threatened me saying if I did not pay them that the local county police dept would be picking me up. After going back in fourth with them. I was afraid in payed them. Come to find out. They are a bunch of scammers. I stopped payment but my bank refused to give me MY money. So please don't answer when this # calls. They sound like scammers too. I never answer when this # calls.

These people are rude, I get calls every day, they say they're 500 fast cash, and I need to pay immediatly otherwise legal action will take place.  People don't believe them, because if you ask them for their address to send payment, they start saying they don't give out their address, that payment need to be paid by visa/master card or debit.  Please DO NOT say that you will pay by either one, they will empty your bank account.  I have spoken to these people have requested from them to send me by mail a bill or statement how much I owe them and they keep saying that I should know how much I owe and you know whay they will start saying is this your email address and they keep on keep on and will never stop talking... I only hang up.  I don't bother in answering my phone.   Please do not give them your information. This comcpany is not the really company.  Real Companies will send you a statement....if you request one from them.

I got a new cell phone and have received many many many calls from this number asking for someone else, I tell them it is not me, that it is a new phone number and they tell me they don't believe me and that I must prove I am not the person they are calling for?!?!!?  I asked them to prove to me who they are and they said they wouldn't do that until I told them who I was.  I have told them over and over again to stop calling me, I am not the person they are looking for.  Now they are texting me threatening to debit my account by 9/14/12?  these people just will not goaway.  I have talked to them, yelled at them and hung up on them and nothing makes a difference.  Last time I told them I was going to file harrasment charges.

This trash has called my cell number for over a year.Please do not believe a word they say about removing your number.I dont think any of them are smart enough to complete such a daunting task(if they could they wouldn't be doing this for a living).If anyone out there knows the whereabouts of someone named Susan Kent,please tell her to quit using her old cell number to get payday/loanshark debts and then skip out on them.

I've had to explain to this caller that the person they are trying to reach has either supplied them with an invalid number, or this was supplied as a contact number more than 6 months ago. My line that they call has been inactive for about 6 months and has just recently been activated. Told them I assumed it was a collection agency looking for someone no longer using this number.... still could not get a name for the company calling. no help from their end.

I keep getting calls from this number 918-442-9101 they say I owe them 900.00 dllrs, Pay day loan 500 fast cash.  Ths is a scam, people that are trying to get your money.  Don't believe a word they say.

This company keeps calling, I tell them wrong number, but insist, very rude uneducated person.
They say I owe them money and if I don't pay they will send a Constable to pick me up at work and will repo my house and vechile.  They try very thing to scare you, please don't believe them.  Get something in writing if they're 500 Cash Fast.  PLEASE DO NOT BELIEVE A WORD THEY SAY, THEY'RE SCAMERS......

Especially if they have an accient.   BE CAREFULL PEOPLE.   DO NOT ANSWER PHONE LET IT GO TO VOICE MAIL.

These people just don't take no for an answer. They keep calling for months now. We've even started taking turns answering and "teasing" them, talking in funny accents, pretending we don't understand them, transferring them to conference rooms, etc. Makes the best out of a bad situation.

Missed call. Found this whilst looking it up.

This number calls every couple of days, the Caller ID is listed simply as "500FC," and upon picking up the phone it simply hangs up. I was assuming that this was a collection agency or something, good to get confirmation.
